Question

Check whether x-3 is a factor of the polynomial. X^2+x-12 using factor theorem

Answer 1

Answer:

Step-by-step explanation:

By using factor theorem

p(x)= x^2 + x -12

Where x-3 =0

∴ x=3

p(x)= 3^2 + 3-12=0

9+3 -12=0

12-12 =0

Since the answer is 0

x-3 is the factor of polynomial p(x)
